Marinus Anton Donk, born in pre‐Indonesia and resident during the last years of Dutch Colonial rule, fell heir to a history of mycological studies traceable to the 1600s. Rumphius, Juhnhuhn, Zollinger, von H??hnel, van Overeem, and Boedijn were some of his predecessors. He survived cruel treatment while under Japanese incarceration during World War II, to become Head of the Herbarium in Bogor (formerly Buitenzorg), Java. Indonesia. In middle age, he moved to the Rijksherbarium in the Netherlands and further established his reputation in the taxonomy and nomenclature of the Hymenomycetes, a large group of basidiomycetous fungi. He was lauded and feared by numerous mycologists before he died prematurely in 1972. Occasional contemporary (chiefly mycological) personalities are included here as well as personal Donk communications to others.
The unsatisfactory indexing of each of the three parts of Quélet’s initial mycobiota of north-east France is replaced with a single comprehensive alphabetical index to all main entries of genera, species, and varieties, with their author citations and their correct original Quélet journal references (together with their confusing page references from repaginated separata).
The Rev. Miles J. Berkeley was active in Britain in the middle of the 19 th Century. Among his many scientific endeavors was the study of fungi and plant pathology. Between 1842 and 1892 he published, alone or with collaborators CE Broome, MA Curtis, MC Cooke and JB Ellis and BM Everhart, fifty???six new species of Hypocrea and he recombined into Hypocrea two additional species. These are foundational species in the genus Hypocrea , now Trichoderma . Types of all names that Berkeley included in Hypocrea have been examined for this study. The disposition of those names is discussed. The following new combinations are proposed: Amplistroma cervinum , Ascopolyporus maculiformis , Stilbocrea neilgherriensis , Trichoderma deplanatum , T . discellum , T . grossum , T . laetioris , T . maculiforme , T . multiforme , T . petersii , T rugulosum , T . saccharinum , T . scutellaeforme , T . subrufum . Lectotypes are selected and or designated for Hypocrea farinosa , H . laetior , H . maculiformis , H . multiformis , H . neilgherriensis , H . ochroleuca , H . pezizoides , H . ravenelii , H . saccharina , H . scuellaeformis , and H . subrufa .
Four species of lichenicolous fungi (Clypeococcum epicrassum, Polycoccum cladoniae, Sphaerellothecium arnoldii, and Stigmidium aff. lecidellae) and two species o f lichenized fungi (Gyalolechia klementii and Parvoplaca servitiana) are reported for the first time from Turkey. Comments on their morphological characters, habitats, and substrates are provided, together with macro- and microphotographs.
A powdery mildew fungus appearing on the leaves of Bistorta amplexicaulis in Pakistan is described as a new species, Erysiphe bistortae . This species is characterized by its large-sized chasmothecia and relatively small conidiophores. Because of biological and morphological differences from related species, supplemented by results of molecular sequence analysis, the Asian powdery mildew on B. amplexicaulis warrants description as a species of its own.
